Compact Ultra-High Temperature Tube Furnace (25mm ID. 2000°C Max) with Digital Controller -- - GSL-2000X-25

EQ-GSL-2000X-25 is an ultra-high temperature furnace with 1" I.D x 6" L heating chamber up to 2000°C under inert gas for materials research. This compac furnace uses a special tungsten heating element design to reach high temperatures at every low power  (<3000W) . Precision digital controller provides stable temperature control via C Type thermocouple and SCR power supply.
